Number Property (Err Object) 

  • Artigo

Returns or sets a numeric value specifying an error. Read/write.

Public Property Number() As Integer

Remarks

When returning a user-defined error from an object, set Err.Number by adding the number you selected as an error code to the VbObjectError constant. For example, you use the following code to return the number 1051 as an error code:

Err.Raise(Number:=vbObjectError + 1051, Source:="SomeClass")

Example

This example illustrates a typical use of the Number property in an error-handling routine.

' Typical use of Number property.
Sub test()
  On Error GoTo out

  Dim x, y As Integer
  x = 1 / y   ' Create division by zero error.
  Exit Sub
out:
  MsgBox(Err.Number)
  MsgBox(Err.Description)
  ' Check for division by zero error.
  If Err.Number = 11 Then
      y = y + 1
  End If
  Resume Next
End Sub
